I don't know a lot of Mother inspired game apart from Undertale/Deltarune and Omori (I know there's a lot, I just don't know them). Do they seriously all tackle super gloomy topics?
Except for Hylics, yeah, they all pretty much use the same plot.
It's always long, dramatic and centered around dealing with loss, change, and hardship. It's exhausting.
I think I said this before but I always had a problem with games and media that have depressing themes, I just don't really see the point since it's doesn't make the player feel joy, nor does it benefit their life in a useful way.
Also I looked up Hylics and yo what the actual hell is this?!
And it's been done to death. Mother 3 was perfect, and Undertale was a great successor. But now almost every game keeps trying to do the same thing, and it's annoying as hell.
I still have no desire to ever play Omori and will never understand the appeal of that game. How hard is it to make a JRPG that's just plain fun?
Ribbit was the most fun JRPG I've played in years, and it was a mod of Deltarune Chapter 1.
And as for Hylics, yeah, that game is a trip. If you want a JRPG that's dirt cheap and will surpass WL4's weirdness, then you're in for a treat.
I never played any of the Mother games since I'm not big into RPGs, though I did play Undertale and I think it was alright. I've heard a lot of praise for every aspect of Omori apart from its gameplay so I'm gonna assume it's nothing to write home about. Maybe I'll play Ribbit some day.
I played through Deltarune Chapter 1 through 5 and to be honest, the more I played the more dissapointed I was. I just feel like the game doesn't really go anywhere. Like the story is trying to be cryptic for the sake of being mysterious and to be honest, it has been annoying me. I have genuinely no idea how Toby Fox will be able to give a satisfying ending, and to be honest I kinda lost my faith in indie creators ability to give satisfying answers to long mysteries since the TADC ending. Undertale worked because it was a short game but Deltarune is not.
